LAND .ROLLER AND PU LVERIZER.

SPECIFICATION forming part of Letters Fatent No. 630,467, dated August8, 1899.

Application filed November 12, 1898. Serial No. 696 ,286. (No model.)

nois, have invented a new and useful Land' Roller and Pulverizer, ofwhich the following is a specification.

This invention relates to a new and useful combined land roller andpulverizer; and it has for its object to effect certain improvements ina machine of this character whereby the same shall be renderedexceptionally strong and capable of adjustment to adapt the same fordifferent uses.

To this end the invention primarily contemplates improvements in thattype of land rollers and pulverizers employing sectional rollers havingwhat is known in the art as corrugated peripheries, whereby the saidsectional rollers may be lengthened or shortened according to the use ofthe machine, while at the same time the separate disks or sectionsthereof are held closely together in proper working relation.

With these and other objects in view, which will readily appear when thenature of the invention is more fully understood, the same consists inthe novel construction, combination, and arrangement of parts, ashereinafter described, illustrated, and claimed.

While the invention is necessarily susceptible to modification, stillthe preferred em-' bodiment thereof is shown in the accompanyingdrawings, in which I Figure 1 is a perspective View of a combined landroller and pulverizer embodying the improvements contemplated by thepresent invention. Fig. 2 is a central longitudinal sectional Viewthereof. Fig. 3 is a transverse sectional view on the line 3 3 of Fig 2.Fig. at is a detail'in perspective of the sectional adjustableroller-frame. Fig. 5 isa detail sectional View showing one of theclampyokes embracing the overlapped bars of the frame-sections.

Like numerals of reference designate correspondingparts in all thefigures of the drawings.

Referring to the accompanying drawings, the numeral ldesign'atesanoblong rectangular roller-frame, consisting of the duplicateframesections 2 2, which are adjustably con- 1 ends.

nected together so as to render the frame longitudinally extensible,whereby the same may be lengthened or shortened, according to the sizeof the rollers which it is desired to use in connection therewith.- Eachframesection 2 is of a substantiallyU shape and consists of the parallelfront and rear bars 3 and an end bar 4:, connectingithe outer terminals'of the parallel bars 3, and the said parallel bars 3 of the two U-shapedframesections 2 overlap and are adj ustably clamped together by means ofa pluralityof rectangular clamp-yokes 5, provided in their lower sideswith the threaded openings 6, receiving the binding-screws 7, whichimpinge against the lowermost framebars 3 and serve to tightly clamp theoverlapping parts together.

The contiguous ends of the oppositely-arranged frame-sections 2 overlapeach other a considerable distance to strengthen the central portion ofthe frame, while at the same time permitting of the material adjustmentthereof according to the size of rollers required for use, and a pair ofthe clamp-yokes 5 is preferably employed on the overlapping portions ofboth front and rear bars 3 of the extensible frame, as plainly shown inFig. l of the drawings. When the clamp-yokes 5 are tightened on theoverlapping bars 3 of the frame-sections, such frame-sections are heldrigidly together; but should it be desired to lengthen or shorten theframe it is simply necessary to loosen the binding-screws 7 toaccomplish this result. I

As the central portion of the frame is subjected to the greatest strainand at times will support from one thousand to three thousand pounds, itis necessary that the same be of exceptional strength, and thisreinforcing of the ce'ntral'portion of the machine-frame is accomplishednot only by the lapping of the front and rear frame-bars 3, but alsothrough the medium of a pair of central brace-bars S and 9, arrangedtransversely of the rectangular frame 1 at a central point between itsThe central transverse brace-bars 8 and 9 are arranged,respectively,above and below the overlapped portions of the framebars 3 of the twoframe-sections and are securely clamped to the frame-bars by means ofthe clamping-bolts 10, arranged in pairs at the front and rear endportions of the said brace-bars 8 and 9 and connecting said bars,

respectively, on opposite sides of the overlapping frame-bars, therebyproviding an exceedingly-strong bracing of the central por tion of theframe. In this connection it will be observed that the clamping-bolts land brace-bars 8 and 9 in effect constitute a central clamp whichsupplements the action of bolts 10 for the upper and lower transversebrace-bars S and 9 also pass through the rear end of the draft-tongue11, which rests on top of the front end portion of the upper bracebar 8and extends to the front in the usual manner, and to provide for theproper bracing of the draft-tongue 11 a pair of bracerods 12 isemployed. These brace-rods are fastened at their front ends,respectively, to opposite sides of the draft-tongue l1 and divergerearwardly to the front frame-bars 3, to which frame-bars the rear endsof the brace rods 12 are bolted by means of the securingbolts 13. Thesesecuring-bolts 13 are adapted to be fitted ,in any of the series ofboltopenings 14, formed in the front frame-bars 3 of the frame-sections2 in order to permit the frame-sections tobe adjusted without disturbingthe relative positions of the brace rods, 12. The rear pair ofclamping-bolts for the central transverse brace-bars 8 and 9 also passthrough the lower end of the seatsupport 15, resting on the rear endportion of the upper brace-bar 8 and extending upwardly and rearwardlytherefrom at an angle, the upper end of said seat-support or seat-arm 15supporting thereon the usual drivers seat 16.

The roller-frame carries or supports a single roller-shaft 17, extendinglongitudinally of the frame the full length thereof and arranged midwaybetween the front and rear frame-bars 3. The said shaft is supported toturn in a plurality of alined wooden bearing-boxes 18, arranged,respectively, beneath the opposite ends of the roller-frame and thelower central transverse brace-bar 9, and said bearing-boxes aresecurely braced and held in place by the approximately U shapedmetalstraps 19. V The metal straps l9 embrace and snugly fit the woodenbearing boxes or blocks 18 and are provided at their terminals withtheattaching-flanges 20, which are securely bolted, by means of bolts21, to the pertions of the frame supporting the boxes.

At each side of the central pair .of transverse brace-bars 8 and 9 thesingle rollershaft 17 supports thereon a sectional roller 22, having acorrugated periphery and essentially consisting of a plurality of disksections 23, arranged side by side and closely grouped together and eachof which disk sections is provided with a double-beveled or V-shaped'duce an uneven wearing of the parts.

periphery 24, which serves to break the clods or pulverize the soil asthe machineis rolled over the ground. The disk sections 23 of eachsectional roller are entirely separate and independent of each other, sothat the same may be readily removed and replaced, or any number of disksections grouped together, according to the desired length of theroller; but in the use of the machine it will be understood that each ofthe sectional rollers 22, respectively, at opposite sides of thetransverse center of the roller-frame is preferably of the same lengthand composed of the same number of disk sections. Furthermore, it willbe seen that the central pair of bracebars 8 and 9 not only serve as acentral transversebrace or clamp for the fra-me, but also form a centralabutment for the inner ends of both of the sectional rollers 22, whilethe outer ends of the U-shaped frame-sections 2 form outer abutments toprevent material separation of the disk sections, so that all of thedisk sections of each roller will operate uniformly and in unison as themachine is rolled over the ground.

By reason of the sectional construction of the rectangular roller-frame,whereby the same may be lengthened or shortened, it Will be obvious thatthe adjustment of the frame provides for taking up lost motion or wearof the parts, so that the disk sections of the rollers may always beheld close together, so as to prevent trash or soil from working inbetween the same, and thereby causing the disk sections to workindependently and pio- 11 additional advantage of the sectional adjustable construction of frame has already been referred to-viz., topermit additional disk sections to be mounted on the shaft if it isdesired to lengthen the rollers, or vice versa; but in all sizes of thesectional rollers it will be understood that the frame-sections areadjusted so as to hold the disk sections closely together, whereby thesame may properly subserve their usual function of pulverizing orbreaking the clods and eveningup the soil.

The opposite extremities of the single con tinuous roller-shaft 17 arepreferably fitted with removable keys 25, whereby the same may bereadily removed and replaced; but it will of course be understood thatequivalent retaining devices may be used in connection with the shaftfor accomplishing the same result without departing from the spirit orprinciple of the invention.

At this point it will be observed that the openings in all of thebearing boxes or blocks 18 are in precise longitudinal alinement; but inview of the lap of the two frame-sections it will be necessary to havethe bearing box or block carried by the uppermost frame-section somewhatwider than the other bearing boxes or blocks, as plainly shown in Fig. 2of the drawings, to compensate for the disalinement or lap of theframe-sections.

From the foregoing it is thought that the construction, operation, andthe many advantages of the herein-described combined land roller andpulverizer will be readily apparent to those skilled in the art withoutfurther description and that changes in the form, proportion, and minordetails of construction may be made without departing from the spirit orsacrificing any of the advantages of the invention.
